Abstract Fuel cell is one of alternative method to replace fossil fuel energy. The important component of fuel cell is a membrane that used for separating cathode and anode also as a proton conductor. The purpose of this research is to produce polymer electrolyte membrane from poly (eugenol sulfonate) (PES) as polymer matrix, characterize the resulting membrane analysis using ionic properties analysis by calculating ionic conductivity using impedance spectroscopy, ion exchange capacity (IEC), solvent absorption analysis by calculating water uptake and methanol permeability, and studying mechanism Proton transport that occurs on the membrane. This research was initiated by making polymer of PES, and then fabrication and characterization of electrolytic polymer membrane. The formed membrane has an optimal proton conductivity of 0.00095 S.cm-1 with PES composition of 22% (wt).

Blend Polymer

The low cost of ABS polymer and natural polymer chitosan offer attractive chemical and physical properties for direct methanol fuel cells (DMFC). In this contribution, investigation of blend membrane made of ABS and chitosan, and their characterization for water uptake, swelling degree and ion exchange capacity (IEC) and methanol crossover are reported. This membrane was also assessed for its intermolecular interactions and thermal stability using FTIR and TGA compared to the pristine membrane. The water absorption and IEC values were affected by membrane network structure. The polymer blend had better thermal stability and a reduction of methanol permeability, this indicated the viability of utilization these materials as polymer electrolyte membrane in DMFC

A series of phenolphthalein-based sulfonated poly(ether ether sulfone) (SPEES) membranes were synthesized by aromatic nucleophilic polymerization reaction. The degree of sulfonation was controlled by direct synthesis of sulfonated polymer, which leads to high thermal stability. The physicochemical properties of the SPEES membranes were studied in order to evaluate the suitability of these membranes in fuel cell applications. The ion-exchange capacity of the synthesized SPEES membranes was found in the range between 2.19 mequiv. g−1 and 2.35 mequiv. g−1. The morphology of the membranes was investigated with high-resolution scanning electron microscopy and confirmed the presence of hydrophilic domains that impart good proton conductivity. The membrane electrode assembly of SPEES-30 and SPEES-50 membranes has been successfully fabricated, where SPEES-50 produced a maximum peak power density of 643 mW cm−2 while applying in hydrogen–oxygen fuel cell.
